Conditional access system is designed to encode the transmitted video and/or audio stream – to prevent its viewing and/or listening by third unauthorized parties. Control of this process is realized with use of encryption and authorization (for users in digital TV system) program.
Beijing Compunicate Technology Inc. – leading provider of conditional access systems in China involved in research and development of these systems for more than 10 years.

ARRIS D5 Universal Edge-QAM (UEQ) is a solution for processing of SPTS and MPTS MPEG-streams received from IP-network, establishment of multiplex channels, and their transmission as QAM-modulated signal in HFC network.
This platform allows simultaneous injection of up to 3000 MPEG streams – via four GigabitEthernet interfaces located on network access module
